HOSE-CLAMP.

Application filed November 1, 1915.

To till whom it may concern."

Be it known that we, JA'MnsJ. 000K and Onnnnns H. Coon, citizens of theUnited in the county have invented 2r new and usefulHose-Olamp, of

specification. This invention has reference to hose clamps and itsobject is to provide a. clamp States, residing at Jersey City,

--producible fromsheet metal wherein an or the like may be di-narymachine screw or utilizedv as the, clamping screw:

In accordance with the present invent on the clamp,whaclr-is intended.for. securing.

the ends of hose, flexible pipes and the like, to suitable couplings, isformed of one or more pieces of sheet metal with either or both terminalparts rolled or coiled upon themselves, and this is especially true ofthe through which the clamp threaded, the nut being formed of aplurality of turns which may be pro- H .duced about 2 common axis with athreaded passage for t 1e screw therethrough, thus 25 producing e'particularly strong nut made of thicknesses of sheet respect totheother, so that under the-strain of the screw the layers making up thenut the latter against accidental loosening, the

' whole-structure tending :to uniformly con- .trnictrnhont the-hose towhich it is applied,

so as to exert a uniformly distributed pres .sure thereupon. Theslnyention will be best understood from a consideration ofthe followingdetaileddesoription, taken 1n connection with the accompanying drawingsforming part of this specificat on,

derstnnding that with the further unwlnle the drawings show 4,aprn'cticul form of the invention, the latter is. not confined to any.StllCi cOllfOl'llllt). with y of the drawings, but may be changed andmodified so long as such changes and modifications come 4 within thescope or the appended claims.

Fig. 11.is a. similar view disclosing a still further modified form ofthe clamp wherein the tongue is independent of the body of the clninp;and i i Fig. 12 is'an end elevation of the clump of Fig. 11, showing theadjustment of the tongue to admit of the ready application of the clampto hose and the like.

Referring to the drawings; and particularly to Figs. 1., 2. and 3, thechimp comprises a band or body portion made preferablyofspring.nietulsuch as sheet metal and adapted to encircle the hose,flexible pipe or the like. This band 15 is rolled into circular :or hoopform to loosely .fit over the hose or other member to which the clamp isto be attached. 'The band provided with a tongue 16 at one end adaptedto lap provide a complete inclosure for the article inFi'gs. 1, 2 and 3,this tongueisintegral with the band 15. Tlidotherend of the band. 15 isbent at substantially a tangent to thebody of the clamp, to provide ascrew having t suitable elongated opening 18'- therethrough. for thereception the shenk of a clamping screw 19 to turn freely in saidopening. As shown inFig. 1, theclempingscrew 19 which is in, the form ofemachine screwis shouldered as at 20 for engagement .zi geinst theprovided with a flet head 21. for engagement by. the fingers of anoperator to turn 20. The outer end of is attached. As shown support 17and 20 v the clamp at any one point upon the hose 01' the support 17 isbent atan angle to' the support and toward the opposite side of theclamp to provide a guard or shield 22 extending above and in the samedirection as the clamping screw- 19, and it )referably extends a slightdistance beyond the threaded end of the screw so as to ward off clothingor other obstructions which might possibly come into contact with and becaught bjy or entangled with the free end of the c amping screws In theform of the invention shown in Figs. 1, 2 and 3 the band or body'of theclamp, the support 17 for holding the clamping screw, and the guardwhich protects the clamping screw, as Well" as the tongue 16 are allformed'integrally' from 'a strip of metal.

For thepurpose of effecting the desired circumferential binding actionof the clamp, and for preventing the'undue binding of other article towhich it is applied, the band 15 has secured thereto, at ,a pointsubstantially half way around the band from the support 17, a drawingstrap 23, which lies against the periphery of the band '15 for a shortdistance and terminates at its free end in a traveler 24 which, as.willvhereinafter appear, serves as a nut. The length of the drawingstrap 23 from the pointjwhere it is secured to the band 15 to thetraveler 24 is such as to permit movement of the traveler along-thescrew 19 to completely contract the band and bring the traveler. 24 .andsupport 17 together. By this construction, it will be observed that asthe traveler is moved toward the support,- the band 15 will bedraw'n'lon'gitudinally in a circular'path so thatanevencontraction ofthe'b'and is in sored-and no one point of the band is brought to bearupon the hose or 'other article with unduefipressurer The drawing strap23 may be secured tothe band 15 in any desired rolled over support 17 ofthe band 15. The support 17 is not entirely closed, butis leftmanner,-and is shown in Figs; 1, 2 and 3 as" eyeleted to the band byproviding the band -with aperforation 25 at the point of ,attachagainstas shown in Fig. 1 to bind the end of the strap 23 against the outerface of the band15. The strap is made preferably of a relati velyflexible or pliable material and is. ofslightl lessiwidth or thicknessthan that of the bot yof the clamp. Because the strap ispliable orflexible it readily conforms to f of the clamp as above "described, is

.the' outer surface of the band, as'the traveler is drawn toward thesupport, and thus prevents any undue pressureof the strap-23 against,the underlying portion of the band. In Figs. 4 and 5 asli'gh-tlyniodificd form strap 23 is held in place,

rolled or turned over upon itself to rovi'de a cylindrically coiledsupport l7 w ich by reason of its coiled form presents aplurality ofbracing walls providing a substantial and rigid support for the clampingscrew. The walls of the turns of the support 17 are suitably perforatedas at 18 to admit of the free passage of the shank of the clamping screw19 therethrough. The head 21 of the clamping screw 19 of Fig. 4, isprovided with alkerf 27 'for the. reception of a screw driver or othersuitable operating tool. In Fig. 4, the drawing strap 23 is secured tothe band 15 by a rivet 28 passed-through the end of the strap '23 andthrough an aperture 29 formed at the desired point in the band 15. Thestructure of the clamp shown in Figs. 4 and 5 is particularly adaptedfor large and heavy work, and for this support '17, and the rolled overor coiled traveler 24.

The structure of clamp shown in Figs. 6 and 7 is substantially the sameas shownin Fig. 1, withthe exception that a modified form of drawing.strap 23* is-einployed. In this form,'the drawing strap'23 passesentirely around the band 15 and has its inner end turned outwardly as at30 and provided with an aperture 31 for thereception of the shank of theclamping screw 19, passes through the support 17 and also through thetraveler 24 carried on the free end'of the strap. In this construction,the eyelet, the rivet and other like fastening de- -vices are doneawaywith, as the clamping 111g strap 23 surrounding the band as shown'm'Fig, 8,"-"and in lieuv of-an outturned end 30 it has a coiled orturned over portion provided with a head. 32 to fit into the coiled orslightly open adjacent to the band'15 to facilitate the lateralinsertionof the head 32in assembling-the parts of the clamp. In the I purpose isprovided with boththe rolled over or coiled which latter 1 structure ofFig. 8 both the head 23 and the.

socket 17*"have transverse registering openingstherethrough freelyreceiving the shank 'of the clamping screw 19. The advantage of thisstructure is that the support for the clamping screw is reinforced andforms a substantial structure, while the drawing may be readily detachedand performs the same function of drawing the band 1 7 longitudinally asis accomplished in the above described forms of the-invention.

In Fig. 9 of the drawing, there is disclosed a form of clamp whereintheha'ndas ell as the dr'awi'ng strap are made in one piece.
